Abstract
A dryer appliance that includes a fire extinguishing system is provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber for receipt of articles for drying. The dryer appliance includes a water inlet valve in fluid communication with a steam nozzle operable to deliver water into the chamber to form mist or steam. The dryer appliance also includes an extinguishing nozzle in fluid communication with the chamber of the drum and with the water inlet valve. Upon detection of a fire, water is provided to the extinguishing nozzle and the extinguishing nozzle directs a stream of water into the chamber to extinguish the detected fire.
Claims20
A dryer appliance, comprising:
- a cabinet;
- a drum rotatably mounted within the cabinet, the drum defining a chamber for receipt of articles for drying;
- a water inlet valve in fluid communication with a water supply, the water inlet valve movable between a closed position and an open position;
- a steam nozzle in fluid communication with the water inlet valve and with the chamber of the drum, wherein when the water inlet valve is in the open position, the steam nozzle is operable to deliver water to the chamber such that mist or steam is formed within the chamber;
- an extinguisher nozzle in fluid communication with the chamber of the drum, wherein the steam nozzle and the fire extinguisher nozzle are separate components;
- and
- a secondary valve positioned between and providing selective fluid communication between the water inlet valve and the extinguisher nozzle, the secondary valve movable between a closed position and an open position, and wherein when the water inlet valve is in the open position and the secondary valve is in the open position, the extinguisher nozzle is operable to deliver water to the chamber such that a stream of water is directed into the chamber for extinguishing a fire.

- a drum rotatably mounted within the cabinet, the drum defining a chamber for receipt of articles for drying;
- a water inlet valve in fluid communication with a water supply, the water inlet valve movable between a closed position and an open position;
- a steam nozzle in fluid communication with the water inlet valve and with the chamber of the drum, wherein when the water inlet valve is in the open position, the steam nozzle is operable to deliver water to the chamber such that mist or steam is formed within the chamber;
- an extinguisher nozzle in fluid communication with the chamber of the drum;
- a secondary valve positioned between and providing selective fluid communication between the water inlet valve and the extinguisher nozzle, the secondary valve movable between a closed position and an open position;
- a fitting having a first outlet and a second outlet, the steam nozzle being fluidly connected with the first outlet;
- a first delivery conduit fluidly connecting the water inlet valve with the fitting;
- a second delivery conduit fluidly connecting the second outlet of the fitting with the extinguishing nozzle, wherein the secondary valve is positioned between the fitting and the extinguishing nozzle along the second delivery conduit;
- a fire detection device;
- and
- a controller communicatively coupled with the fire detection device, the water inlet valve, and the secondary valve, the controller configured to:
- receive, from the fire detection device, an input indicating detection of a fire;
- and
- in response to the received input, cause:
- i) the water inlet valve to move to the open position such that water flows from the water supply into the dryer appliance;
- and
- ii) the secondary valve to move to the open position such that water flows downstream to the extinguisher nozzle and is directed into the chamber for extinguishing the fire.
